243 (Thalia cannaeformis Forst. f., Actoplanes cannaeformis K. Sch.,

ORCHIDACEAE 
HABENARIA Willdenow 
Thelymitra malintana Blanco Fl. Filip. (1887) 642; ed..2 (1845) 447; ed. 
3, 3 (1879) 40=HABENARIA MALINTANA (Blanco) comb. -nov. 
Blanco’s species was reduced by Naves to Habenaria trinervia 
Wight, a species that does not extend to the Philippines and 
one to which his description does not apply. Thelymitra malin- 
tana is, however, a species of Habenaria and is identical with 
Habenaria pelorioides Par. & Reichb. f. (1874), or at least with 
the Philippine material referred here by Mr. Ames. Blanco’s 
name is much the earlier and should be adopted, especially in 
view of the fact that there is absolutely no doubt as to ‘the 
identity of his species. The type was from Malinta, a short 
distance from Manila, and the species still grows in the vicinity 
of Manila. 
Illustrative specimen from Obando, Bulacan Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 629). 
VANILLA Swartz 
Epidendrum vanilla Blanco Fl. Filip. (1837) 648 (vainilla), non Linn.= 
VANILLA OVALIS Blanco op. cit. ed. 2 (1845) 448 (sp. nov.); ed. 3, 
3 (1879) 42. 
Vanilla majaijensis Blanco op. cit. ed. 2 (1845) 593 (sp. nov.); ed 3, 3 
(1879) 483=VANILLA OVALIS Blanco. 
Vanilla philippinensis Rolfe is undoubtedly a synonym of i 
Blanco’s Vanilla ovalis, and there is no valid reason why Blanco’s) 
name should not be maintained. The species is common in 
parts of Laguna Province, Luzon (Mount Maquiling and Mount 
Banajao), growing along streams in narrow valleys. Vanilla 
ovalis Blanco was erroneously reduced by Naves to V. aromati 
Sw., while V. majaijensis Blanco was by the same author reduced - 
to V. planifolia Ait., both manifestly incorrect reductions. 
Both of Blanco’s descriptions are imperfect and incomplete, but
